Coupled analysis of TVOC emission and diffusion in a ventilated room by CFD.

This paper presents an analysis of the emission of chemical compounds and their diffusion in a room by the technique of computational fluid dynamics. A polypropylene styrene-butadiene rubber (SBR) plate was chosen as the TVOC emission source. The emission rate and room-averaged concentration are analyzed under various conditions of ventilation rate and temperature. Further, the concentration distribution of TVOC within a room is also examined and evaluated from the viewpoint of ventilation efficiency.
